16 Claims.

This invention relates to cash registers and like machines, but is more particularly directed to a novel printing mechanism for machines of the class illustrated and described in Letters Patent of the United States No. 1,394,256, issued October 18, 1921, to F. L. Fuller, Patent No. 1,619,796, granted March 1, 1927, to B. M. Shipley, and Patents No. 1,817,883, and 1,865,147, issued respectively August 4, 1931, and June 28, 1932, to B. M. Shipley.

GENERAL Dns CRIPTION The machine of the present invention embodies a printing device for recording data on a record strip, said printing device being centrally located at the front of the machine in a convenient position for observation and adjustment by the operator.

A normally locked closure renders the printing device inaccessible to unauthorized persons. An opening in the closure registers with a table over which the record strip passes and provides a. convenient means for autographing desired data opposite the printed entries on the record strip.

The machine embodying this invention has a plurality of denominational rows of amount keys and each row of keys has associated therewith an amount differential mechanism which, in adding operations, actuates the wheels. of the selected totalizer or totalizers commensurate with the depressed amount keys. 7 Each amount differential is operatively connected to and positions an indicator and type carrier in accordance with the depressed amount keys.

i There are two banks of control keys, namely, transaction and clerks, and there is a line of interspersed totalizers for each of the control banks. The bank of transaction keys and the bank of clerks keys each has a differential mechanism, similar to the amount differentials, which shifts its corresponding totalizer line laterally to aline the set of totalizer wheels on said line, corresponding to the depressed transaction and clerks keys, with the amount differentials. The

transaction differential and the clerks differential are operatively connected to corresponding printing wheels in the printing device, which, in

cooperation with the impression mechanism,

records symbols corresponding to the type of transaction being performed and to the clerk performing the transaction. Likewise, the differentials of the two control banks are operatlvely connected to and position their respective indicators commensurate with the depressed control keys. In adding operations, the control keys set up a condition that causes their respective totalizer lines to be engaged with the amount differentials.

The present machine is arranged to perform single item and multiple item transactions and to this end the transaction bank has two groups of keys, namely, single and multiple item keys. A single item transaction is one in which a single item is entered in a single operation of the machine and a multiple item transaction is one in which several items are entered in as many operaticns of the machine, all of said items being entered under one transaction heading such as Item cash or Item charge. Corresponding single item and multiple item keys select the same set of totalizer wheels on the transaction line and, in addition to this selection, the multiple item keys select a single set of wheels of a multiple item totalizer line for engagement with the amount differentials to accumulate the total amount of the multiple item transaction. After completing the entries in a multiple item transaction, it is necessary to clear the multiple. item totalizer before another multiple item transaction or a singleitem transaction can be initiated. This is done by moving the total control lever to a position to control a reset operation involving the multiple item totalizer on the #1 totalizer line.

The different totalizer lines are selected for engagement with the actuators in total recording, either reading or resetting, operations by means of a total control lever. The transaction keys and the clerks keys function the same in total recording operations as in adding operations, to cause the corresponding set of totalizer wheels to be alined with the amount differentials. In totalrecording operations, the differentials rotate the selected totalizer wheels reversely until said wheels are, stopped in zero position by a long tooth thereon contacting a latch device. This positions the amount type wheels and the indicators commensurate with the amount on the wheels of the selected totalizer. A type wheel positioned by the total control lever records the type of operation, add, read, or reset, being performed.

The type wheel line of the printing device carries a plurality of consecutive number type wheels, which, in cooperation with the impression mechanism, records each single item transaction and each multiple item transaction, which, as stated before, consists of a series of item entere ing operations under one transaction heading.

The consecutive number mechanism does not operate during any total recording operations. Novel mechanism is provided to control the consecutive number mechanism during the different types of machine operations. 7

The type wheel line also supports aplurality of wheels which may be set by hand to record or print an identifying number, such as department number, register number, store number, or the like.

The supply roll, the receiving reel and the guide studs for the detailrecord material are supported in a rockable frame, which may be moved to a more accessible position for the removal and insertion of record material. The record strip and a reversible inking ribbon are interposed between an impression hammer and r the record strip into contact with the type wheels to record .the transaction being performed.

The detail record strip feeding mechanism and the impression mechanism are normally disabled during the listing of items in a multiple item operation. However, during the compulsory recording of the total of the multiple items, the record strip feeding and impression mechanisms are rendered effective to record the total of the multiple items.

A manipulative device is provided to render the disabling mechanism for the record strip feeding and the impression mechanism ineffective. With this manipulative device in one position, the record strip feeding and the impression mechanisms function irrespective of whether the operation is a single item, multiple item, or total recording operation. With the manipulative device in its other position, the mechanism that disables the record strip feeding and the impression mechanisms during multiple item operations becomes effective. However, in total recording operations the disabling mechanism is always rendered ineffective, as it is very important that the result of read and reset operations be recorded.

In the ensuing pages the mechanism pertinent to the instant invention will be described in detail.

DETAILED DESCRIPTION The mechanism of the present invention is embodied in the well known type of cash register fully disclosed in the patents referred to at the beginning of this specification. For this reason mechanism of standard construction which is not pertinent to the present invention will be but briefly described.

Machine framework Most of the mechanism of the instant machine is supported between a right frame 50 (Figs. 1, 2 and 9) and a left frame 5!, both of which are secured to a machine base 52, which is in turn attached to the top of a drawer cabinet 53. The entire machine is enclosed by a suitable case or cabinet 56, which is secured to the machine base and to various brackets attached to the top of the drawer cabinet. A back plate 55 (Fig. 2) and various crossrods and bars extending between the frames 58 and 5i, assist in supporting the machine mechanism.

Operating mechanism The machine of the instant invention is preferably operated by means of an electric motor (not shown). Depressing the usual starting bar 55 (Figs. 8 and 9), which is removably connected to a plate 57, slidably mounted on studs 58 secured in the frame 50, causes said starting bar to impart downward sliding movement to said plate 57 against the tension of a spring 59, one end of which is attached to a stud 59 secured in said plate 51. Movement of the plate 571, by means of the stud 65, in cooperation with a bifurcated extension of a crank 6!, causes said crank to pivot counterclockwise on a trunnion 62 secured to the right frame 50. counterclockwise movement of the crank 5!, by means of a link 63, connecting-said crank and a release pawl 64 loose on a No. l totalizer reset shaft 55 journaled in the frames 55 and 5!, rocks said release pawl 64 counterclockwise to move a forward extension thereof out of the path of an arcuate surface of a halfround stud 56 secured in a crank 61 in turn secured to a key lock shaft 68 journaled in the frames 55 and 5|. Movement of the shaft 68 is illustrated graphically for adding operations in space 4, Fig. 39, and for total recording operations in space 3, Fig. 40. Moving the pawl 64 out of the path of the stud 66 releases the key lock shaft 68 to the action of a spring 59 which imparts clockwise movement to said shaft, see space 4, Fig, 39.

Clockwise movement of the shaft 58 closes the motor switch and causes the motor to be clutched to a driving pinion 42 (Fig. 5) loose on a stud 53, secured in a main printer frame 72 in turn secured to the base 52 and connected by various studs to the left frame 5 I. The pinion d2 meshes with a gear 44 loose on a stud 45 in the frame 12. The gear M meshes with a gear it integral with a similar gear 4 rotatably supported by a stud in a bracket 48 secured to the frame 72. The gear ll meshes with a gear 49 secured on a short shaft 'Hl journaled in the frames 5| and 12. Also secured on the shaft '56 is a gear 'H which meshes with a gear 73 (Fig. 21) secured to a main drive shaft 14 journaled in the frames 5% and Bi. Rotation of the motor drives the shaft 14 counterclockwise, as viewed in Fig. 21, and clockwise as viewed in Fig. 9. After the shaft M has completed the necessary number of revolutions to effect the type of operation being performed, the key lock shaft 68 (Figs. 8 and 9) is restored counterclockwise to untripped position, space 4, Fig. 39, and space 3, Fig. 40, thus permitting the spring 59 to return the starting bar 56 upwardly and the release pawl 66 clockwise into the path of the stud 66 to restrain re leasing movement of the shaft 58. The restoring of the key lock shaft 68, is effected at proper time by means of cycle-controlling mechanism, which will be explained later herein.

In case the starting bar 58 (Figs. 8 and 9) is accidentally or inadvertently retained depressed at the end of a machine operation, a non-repeat pawl 15 fulcrumed on the shaft 55 is spring urged into the path of the stud 65, upon restoration of the key lock shaft 63, to obstruct releasing movement of said shaft. This prevents a repeat operation of the machine as the machine cannot again be set in motion until the starting bar 58 is returned upwardly by the spring 59. Upon restoration of the starting bar 55 the rearward extension of the pawl 54, which overlies the non-repeat pawl '55, returns said pawl clockwise to ineifective position as the release pawl 65 moves in the path of the stud B5. The non-repeat pawl 15 is slightly longer than the release pawl 64. This prevents the pawl fi l from stumbling on the stud (it; upon restoration of the starting bar 55 and causes said stud to obstruct counterclockwise movement of the pawl 15 to prevent said pawl from interfering with the releasing movement clockwise of the key lock shaft 68.

Cycle-controlling mechanism In adding operations, the main drive shaft 'i l makes one revolution clockwise or one cycle of movement, as viewed in Fig. 9, and one counterclockwise revolution, as viewed in Fig. 21, and in total recording operations said main drive shaft makes two revolutions or two cycles of movement. Rotation of the shaft it is governed by means of the cycle-controlling mechanism shown in Fig. 9, and which will now be described.

Secured on the main drive shaft 14 is a gear 78, which meshes with a large gear is turnably mounted on a stud 89 secured in the frame 59. A pitman Si is slotted to embrace the stud 89. The lower end of said pitman is pivotally connected to one arm of a lever 62 loose on a stud 83 secured in the frame 59. A link 8% connects the lever 82 to a crank 85 secured on a zero stop throwout shaft 89 jcurnaled in the frames and El. Movement of the shaft 9% is shown graphically in space 2 Fig. 40. The pitman 8i carries a stud 8'1 embraced by the bifurcated lower end of a link 99, the upper end of which is slotted to receive a stud 89 in an arm 9% secured to the key lock shaft 68. The link 83 has an L-shaped slot which cooperates with a stud in a key release lever 92 fulcrumed on the stud 83 and having a roller 93 which extends within a caimning groove in the gear l9.

The functions of the machine (adding. reading and resetting) are controlled by means of a total control plate or lever 95 (Fig. 7) journaled on a stud 96 extending between two support plates (not shown) mounted on rods extending between the frames 5t and 5i. When the total control plate 95 is in adding position, as here shown, the link 88 is positioned as shown in Fig. 9 so that the substantially horizontal branch of the L-shaped slot therein engages the stud 9! in the lever 92. In adding operations, the main drive shaft '59 and the gear it make one clockwise revolution and the gear 79 is driven one-half of a revolution in a counterclockwise direction by said gear is. The camming groove 94% of the gear i9 is concentric with the center 89 with the exception of two identical diametrically opposed camming sections thereof. Near the end of an adding operation, one of the camming sections of the groove 9 in cooperation with roller 93, rocks the lever 92 first clockwise and then back to normal position. Clockwise movement of the lever 92 moves the link 88 downwardly, which, by means of the stud 89 in the arm 99, imparts counterclockwise movement to the key lock shaft 63 to restore said shaft to untripped position (space t Fig. 39) in the manner explained earlier herein. Counterclockwise restoring movement of the shaft 98 releases the depressed amount and transaction keys, opens the switch to the driving motor, and disengages the clutch mechanism that connects the motor to the machine mechanism. a

In reading or resetting operations, it is necessary that the main drive shaft i l make two clockwise revolutions in order to operate the machine through two cycles of movement necessary in such operations. This is accomplished in the following manner:

Moving the total control plate 95 (Fig. 7) away from adding position to either reading or resetting position causes a camming slot ill therein, in cooperation with a stud 98 in a lever 99 pivoted at M9, to rock said lever 99 counterclockwise. Loose on the pivot its is an arm till yieldably connected to the lever 99 by means of a spring Hill. The yieldable arm l9! and the lever 95 together form a camming slot 99 which, in cooperation with a roller Hi l, carried by an arm Hi5 secured to the zero stop throwout shaft as, rocks said shaft clockwise when the lever 99 is rocked counterclockwise by the total control plate 95. Clockwise movement of the shaft 89 by means of the link 99 (Fig. 9) rocks the lever 82 clockwise to shift the pitman 8| forwardly. This movement of the pitman 8i shifts the link 98 clockwise a slight distance but not sufficiently to move the stud 9! out of the left-hand branch of the L-shaped slot in said link. The pitman 8i carries two studs I in, which embrace a right angled projection ill of a slide H2 loose in an angular slot in the back face of a cam i it loose in a recess in the face of the gear l9 and rotatably supported by the stud 89. The cycle control cam H3 has a cam groove H4 which cooperates with a roller H5 carried by the pitman 8E. The slide H2 has a nose i it arranged to engage a recess ill in the gear 19 to lock the cam H3 to said gear in total recording operations.

When the total control plate 95 is in adding position, the pitman 8! is in the position shown in Fig. 9, in which position the nose Ht of the slide H2 is disengaged from the recess HI and the roller l 55 is engaged with a notch in the heart of the cam M3 to retain said cam stationary. Moving the total control plate away from adding position imparts clockwise movement to the shaft 96 (Fig. 9) and the lever 82, to shift the pitman forwardly in the manner explained above. Forward movement of the pitman 8!, in addition to moving the link 98, shifts the slide M2 forwardly to engage the nose H5 with the recess l ll, to lock the cam I I3 to the gear l9. Forward movement of the pitman 8i likewise disengages the roller H5 from the notch in the heart of the cam l is and moves said roller into the cam groove H 2. Depressing the starting bar 59 sets the machine in motion in the manner explained above for the performance of a total recording operation.

Near the end of the first clockwise revolution or first cycle of movement of the shaft i l, the cam groove Htl shifts the pitman 8! an additional distance forwardly to move the enlarged downwardly extending portion of the L-shaped slot in the link 88 opposite the stud M. This provides clearance for said stud 9! and permits the irregular portion of the groove 94, in cooperation with the roller 93, to rock the restoring lever 92 back and forth without imparting releasing movement to the link 88 and the key lock shaft 68, thus causing the machine to operate through two cycles.

Near the end of the second cycle of movement, the groove I Hi returns the pitman 8i rearwardly to reengage the upper left-hand branch of the L-shaped slot in the link 88 with the stud 9!. It is therefore obvious that when the second irregular portion of the slot 94 rocks the release lever 92 back and forth, initial movement clockwise of said lever will move the link 88 downwardly to restore the key lock shaft 68 (space 3 Fig. 40) counterclockwise to terminate operation of the machine and to release the depressed transaction key. Return movement of the lever 92 and the link 98 permits the stud 69 to come to rest against the end of the release pawl 96. The link 83 continues to travel upwardly a slight distance independently of the shaft 68 to compress the spring 69 and to provide clearance for the stud 89, to permit clockwise releasing movement of the shaft 68 when the starting bar 56 is again depressed.

Shifting the total control lever back to adding position disengages the slide H2 from the recess H! and reengages the roller H5 with the notch in the heart of the cam H3.

In addition to the electric motor, a crank H8 (Fig. 9) is provided for manually operating the machine in emergencies occasioned by failure of the electrical current or accident to the motor. The crank l l 3 carries a stud which is journaled in a bushing H9 secured to the frame 59. Integral with the crank H8 is a pinion l29 which meshes with the gear I9 and thus provides a manual means of rotating the main drive shaft I4.

Amount keys and difierentials The machine embodying the instant invention has four rows of amount keys I2I (Figs. 1 and 2) each of said rows being mounted in a key frame I22 supported by rods I23 and I24 extending between the frames 53 and I. In addition to the four banks of amount keys there are three overflow amount banks making a total of seven amount banks. There is an amount differential mechanism associated with each of the amount banks. Inasmuch as the amount banks and their associated differential mechanisms are substantially alike, it is believed that the explanation of one such amount bank and its differential mechanism will be suincient for the purpose of this specification.

Depressing one of the amount keys I2I (Fig. 2) causes a camming projection I25 thereof, in cooperation with a stud I26, to rock a control plate I21 downwardly. The control plate I2! is rockably mounted in the frame I22 by means of arms I28 and I29, the lower ends of which are pivotally connected to opposite ends of said plate I21 and the upper ends of which are pivoted on stationary studs mounted in the frame I22. As the projection I25 moves beyond the flat surface of the stud I23, the control plate I2l is spring returned a slight distance upwardly to cause said stud I26, in cooperation with said projection I25, to retain the amount key depressed. The operation of the amount keys is flexible in that depression of an amount key releases a previously depressed amount key in the same row.

Downward movement of the plate I27 and incidental counterclockwise rocking of the arm I29 causes a camming surface on said arm, in cooperation with a roller, to rock a zero stop pawl I30, rotatably mounted in the frame I22, counterclockwise out of the path of a nose I3I of a reset spider I32 for a differential actuator I33. The actuator I33 is rotatably mounted on a hub I34 extending between two plates I35, only one here shown, supported by rods I38 and I3? extending between the frames 50 and 5I. Depressing one of the amount keys I2! (Fig. 2) moves the lower end of the stem thereof into the path of a latch arm I38 which is pivotally connected to the actuator I33 and together with a companion arm I39 shiftably supports a differential latch I40. When the actuator I33 is in home position as here shown, a foot-shaped rearward extension of the latch I43 is spring-urged into communication with a shoulder I iI of a differential operating segment I42 pivoted on the hub I34 and connected by a link I43 to an A-shaped lever I44 pivoted on a stud Hi5 secured in the plate I35. Downward extensions of the lever I44 carry rollers I47 and I48 which cooperate respectively with companion plate cams I49 and I50 secured to the main drive shaft I4.

It will be recalled that in adding operations the main shaft "I4 makes one clockwise revolution which, by means of the cams I49 and I50, see space I of chart Fig. 39, rocks the lever I44 and the driving segment I42 first clockwise and then back to normal position. Due tothe shoulder I 4 I, the segment I 32 carries the latch I40 and the actuator I33 clockwise in unison therewith until the latch arm I38 contacts the stem of the depressed key. This shifts the latch I43 forwardly to disengage the foot-shaped rearward projection thereof from the shoulder MI and to engage a nose I 5| thereof with one of a series of arcuate notches I52 in a curved alining plate I53 secured to extending arms of the plate I35. The segment I42 completes its initial movement clockwise independently of the latch I 43, and an arcuate surface of said segment, in cooperation with the footshaped extension of the latch I40, locks said latch and the actuator I33 in set position.

After the actuator I33 has thus been positioned commensurate with the value of the depressed amount key, the corresponding wheel of the selected totalizer or selected totalizers are engaged therewith under the influence of the transaction keys and the clerks keys. When the lever I45 (Fig. 2) nears the terminus of its initial movement clockwise, a roller I54 carried thereby engages the arcuate surface of a beam I55 pivoted to the actuator I33, and forces a curved recess in the upper surface of said beam into contact with a hub I56 for the actuator I33. This positions the beam I55 commensurate with the depressed amount key and said differential positioning is transmitted by means of a link I60 to an indicator I53 (Fig. l) and a plurality of type carriers for that particular bank. The upper end of the link I50 is connected to an indicator segment ltd, rotatably supported by an indicator shaft I62 journaled in the frames 50 and ill, and the lower end of said link I33 is pivotally connected to an arm I53 connected to one of a series of nested tubes I84 rotatably mounted on a printer shaft I65 journaled in the frames 53 and 5 I Secured to the other end of the tube I34 is a corresponding printer operating segment I66 (Fig. 12) which is in turn geared to the type carrier for that partioular denomination.

It is by means of the above described mechanism that the differential positioning of the actuator I33 and the beam I55 is transmitted to the indicator and type carriers for the particular amount bank illustrated in Fig. 2. The reset spider I32 (Fig. 2) is slotted to embrace a stud I6? secured in the latch arm I38. When no amount key is depressed, the zero stop pawl I30 engages the nose I3! of the reset spider to break the latch I40 in zero position.

In total recording operations the shaft 74 makes two revolutions or two cycles of movement as explained herein before and consequently the segment I42 makes two complete excursions. The first cycle of a total recording operation is utilized to aline the wheels of the selected totalizer with the differentials and during this cycle the zero stop pawls I30 (Fig. 2) break all the amount latches in zero position. Near the end of the first cycle, the cam H3 (Fig. 9) shifts the link 8I forwardly to rock the lever 82 and the shaft 86 clockwise. Clockwise movement of the shaft 35 causes a rod I38, supported by arms I63 secured to said shaft 86, to engage forward extensions of the zero stop pawls I33 and rock said pawls counterclockwise to ineffective position. Immediately thereafter, the wheels of the selected totalizer are engaged with the actuators I33 and clockwise movement of said actuators reversely rotates said totalizer wheels until a long tooth thereon, in cooperation with mechanism, not shown but well known in the art, stops the totalizer wheels at zero and positions the actuators I33, the indicator mechanism and the type carriers commensurate with the amount on said totalizer wheels.

In resetting operations, the totalizer is disengaged from the actuators I33 before said actuators are returned counterclockwise and con sequently said wheels remain at Zero. In reading operations, the totalizer wheels remain engaged with the actuators during their return movement and are consequently returned to their original positions. The manually positioned total control plate 95 (Fig. '7) controls the selecting and the engaging of the of the different totalizer lines with the actuators in total recording operations.

Transaction keys The machine embodying this invention has three lines of totalizers, namely, a #1' or multi ple item line, a #2 or clerks line, and a #3 or transaction line. The #1 line has one set of wheels and is used in multiple-item operations to' accumulate the total amount of a plurality of items. The #2 line has five sets of Wheels selected by means of a row of clerks keys I89 (Fig. 10) to accumulate totals of Cash and Receivedon-account transactions. The #3 line has four sets of wheels, selected by means of a bank III] of transaction keys (Fig. 3). The keys of the transaction bank are divided into two groups. One of said groups consists of three multiple item keys, namely, an Item charge key III, an Item cash key III and an Item add key I58. The Item add key IEB does not select a set of wheels on the No. 3 line but is, as its name implies, merely an adding key and enters amounts into the single set of wheels on the No. 1 line as will be more fully explained later. The other group of transaction keys consists of four single item keys H2, namely, Cash, Charge, Received-on-account and Paid-out. The bank of transaction keys also includes a Nosale key I'll-3, which is merely a printing and indicating key, and a Release key II i for releasing any depressed transaction key.

Depressing one of the transaction keys III or Ill-2 moves the lower end of the stem thereof into the path of a differential device II5, similar in every respect to the amount differential explained above, and upon operation of the machine, see space 2 of chart Fig. 39, the depressed transaction key breaks the latch of the differential device I15 in a position corresponding to said key. The differential device has a beam I76 which is positioned commensurate therewith, and which is bifurcated to receive a stud III in a link N8, the upper end of which is connected to an indicator segment I19 loose on the shaft I62 and the lower end of said link is pivotally connected to an arm I89, secured to a segment IBI loose on the shaft Hit. The segment I 8| meshes with a rack I22 secured to a slide I83 mounted for horizontal sliding movement on upwardly extending portions of the base 52. The slide I83 (Fig. 2) imparts transverse sliding movement to a slide I8 3, which, in cooperation with an arm I85 of the #3 totalizer line, shifts said totalizer line laterally to aline the wheels thereof corresponding to the depressed transaction keys III or II2 with the amount differentials I33; It is therefore evident that the pitman I76 and the link I18 and connected mechanisms position a transaction indicator 213 (Fig. l) and select the set of totalizer wheels on the No. 3 line corresponding to the depressed transaction key. An indicator aliner 2I5 (Figs. 2 and 3), in cooperation with alining teeth 2IE in the segment H9 and similar teeth in the segments IIiI for the amount banks and a similar segment for the clerks bank, retain said segments and their associated mechanism in set positions during ma chine operation.

The three multiple item keys III and IE8 (Fig. 3) select the single totalizer on the #1 line to accumulate the total amount of items, and in addition the Item charge and Item cash keys respectively select the same totalizers on the #3 line as the Cash and Charge keys H2. The arm I8!) is connected to a printer segment I86 which is in turn connected to a transaction type carrier and positions said carrier commensurate with the depressed transaction key.

Clerks keg/sand differential mechanism. therefor As previously stated, the machine of this invention has five clerks keys I89 (Fig. 10) mounted in a frame I81 supported by the rod I22 and a stud I88 extending between the left frame El and the printer frame I2. The keys I89 upon depression are operable to control the selection of corresponding sets of totalizer wheels on the #2 totalizer line. The lower end of the stems of the keys I99 are adapted to cooperate with a projection I99 of a differential lever I9! loose on a stud I92 secured in the frame i. A link I93 (Figs. and 33) connects the lever I9Ito a differential latch lever I96 turnably mounted on the indicator shaft I62. The arm I92 (Figs. 10 and 35) has fast therein a stud I95 which engages an upward extension of a latch I95 Divotally connected to a latch plate I9I' rotatably mounted on the indicator shaft I92. A spring I98 stretched between an extension of the plate I9? and the stud I95 urges the latch I95 counterclockwise to normally maintain a. tooth use thereon out of engagement with V-shaped alining notches 200 in a curved alining plate EIlI secured to the left frame SI. Pivoted to the plate I9! is a clerks differential beam 222 slotted to re ceive a stud 293 secured in an arm 299 secured on the shaft I52. A link 295, the upper end of which is fulcrumed on the stud 293, pivotally connects the arm 294 and the beam 292 to a clerks printer segment 296 rotatable on the stud I92. A link 29? (Figs. 10 and 12) connects the segment 296 to a segment 208 loose on a stud 2B9 extending between the frames El and I2. Teeth in the segment 298 mesh with a gear 2ft connected by one of a series of nested tubes (Figs. 6 and 2'7) to a gear 2i 2 which drives a type wheel 2! I corresponding to the clerks keys, said type wheel being mounted in the front detail printer. Other teeth on the segment 229 mesh with a partial gear 2II connected to a corresponding clerks type wheel in the receipt printer, not shown.

Directing attention to Figs. 10, 11 and 35, the latch I96 has a projection 218, which cooperates with a step 2I9 in the periphery of an arm 229 loose on the shaft I62. The arm 22% has integral therewith a crank 22I connected by a link 222 to av cam lever 223 fulcrumed on a stud 224 secured in the frame 5|. The lever 223 carries a roller 225 which cooperates with a cam groove 226 in a box cam 22? (see also Figs. 5 and 2 secured on a short shaft 228 journaled in. the frames 5! and I2. Also secured on the shaft 228 is a gear 229 which meshes with a gear 230 rotatably mounted on a shaft 23!, opposite ends of which are journaled in the frame 5! and a printer front frame 232. The gear 230 meshes with the gear II, which as previously stated, is connected by the train of gears shown in Fig. 5 to the driving motor.

Depressing one of the clerks keys I89 (Fig. 10)

depressed ators moves the lower end thereof into the path of the projection Hit. The cam 22'l makes one clockwise revolution, see space 3 of chart Fig. 39, in adding operations to rock the cam lever 223 and the latch arm 2253 (Fig. 11) first counterclockwise and then back to normal position. The spring Hi3 normally maintains the projection tilt of the latch Est in engagement with the step Elf) and consequently said latch M6, the plate till, the beam 262 (see also Fig. 35) and the lever iQ-Ql move in unison with said latch arm 22:? during its initial movement counter clockwise. counterclockwise movement of the lever its by means of the link Hi3 causes the lever li i (Fig. 33) to move in unison therewith until the projection i913 engages the stem of the depressed clerks key. This obstructs further counterclockwise movement of the lever Hi l and the plateifil and locates them in a position corresponding to the depressed clerks key. The latch arm 229 (Figs. 10 and 11) continues its counterclockwise movement and the step are forces the latch i963 upwardly to engage the tooth 1199 with one of the notches 269. An arcuate portion of the periphery of the arm 22d passes under the projection 2 i S to lock said latch and connected mechanism in set positions. As the lever nears the terminus of its initial movement counterclockwise, a roller 233 conthe link 29? and the gearing shown in Fig.

12, sets the clerks type wheel 2 to a position corresponding to the depressed clerks key. The arm 2% (Fig. 35) being secured on the shaft positions said shaft commensurate with the will! depressed clerks key and, by means of an indicator segment similar to the amount segment hil, shown in Fig. 2, sets up the clerks indicator corresponding to the depressed clerks key. The shaft E62 also shifts the #2 or clerks totalizer assembly laterally to align the selected set of totalizer wheels with the amount differentials.

.ua' and this lateral shifting is accomplished in the following manner:

Secured on the shaft 562 (Fig. 2) is a gear sector which meshes with a rack 23'! secured to a slide 238 mounted to shift vertically on the machine back plate 55 and a plate 258 secured to said back plate 55. The slide 238 carries a roller which cooperates with an angular slot in another slide mounted for horizontal sliding movement on the plate The slide Ed-ll has an extending bracket 2 3i bifurcated to receive an extension of an arm 2&3 which is an integral part of the #2 totalizer assembly. The positioning of the shaft 562 under influence of the clerks difierential mechanism, by means of the instrurnentalities just described, shifts the totalizer assembly laterally to aline the set of clerks totalizer wheels corresponding to the erks key with the differential actu- When no clerks key is depressed in an operation, the clerks differential mechanism is stopped in a neutral position by means of a surface (Fig. 10) of the lever 59! engaging a stationary stud 2 35 in the frame 12.

When the step 2E9 (Figs. 10 and 11) moves beyond the projection 2H3, during return movement clockwise'of the arm 226, the spring [98 disengages the latch lilt'from the plate 200 and reengages the projection 2H; with the recess formed by said step 2H2. Simultaneously, a righthand projection of the arm 229 engages a stud 235 in the plate I91, see also Fig. 35, and returns said plate 2. l and connected mechanism to starting position. It will be noted that the beam 229 and connected mechanism remain in their set positions until the succeeding operation and are moved directly therefrom to their new positions.

In total recording operations, the cam 22'! (Fig. 10) makes two clockwise revolutions and consequently the differential mechanism for the clerks bank makes two excursions of movement. The setting of the type wheels, the indicator .iechanism and the selection of the totalizers is effected during the first excursion of movement and the second excursion of movement is but an idle operation of the differential mechanism. There are various interlocks between the machine releasing mechanism, the totalizer control lever, the transaction keys, the amount keys the clerks keys to enforce the proper operation of the machine.

Printer mechanism The machine embodying the instant invention is provided with a detail printing device conveniently located at the front of the machine and enclosed by a closure 24% (Figs. 1 and i) which forms a part of the cabinet 54. The closure set is provided with a lock 2 3? (Figs. 28 and 29) to prevent unauthorized persons from having access to the printer in general and particularly to the detail record strip. The lock 24? for the closure 2&6 is assembled on a frame 2%, supported by the rods i223 and 32 (Fig. 2) and provided with a guide slot for the fingerpiece: extension of the total control plate 95 (Fig. '7). The slot in the frame 2&8 has various notches therein corresponding to the different positions of the total control plate 95 and affords a means of locating and retaining said plate in its different positions. Unlocking the lock 2 (Fig. 29) imparts counterclockwise movement to a lever i249 pivotally mounted on said lock and bifurcated to embrace a stud in the upper end of a lever 25E], pivotally mounted on the frame 2 18. counterclockwise movement of the lever 2G9 imparts clockwise movement to the lever 250, which movement, by means of a stud in the lower end of said lever in cooperation with a substantially vertical slot 255' in a locking bar mounted for transverse shifting movement on the machine framework by means of slots therein, in cooperation with screw studs, shifts said locking bar toward the left as viewed in Fig. 28. Left-hand shifting movement of the bar 252 disengages a plurality of hooks 253, only one here shown in Fig. 28, from a plurality of corresponding locking brackets 25 secured to the closure After being unlocked, the closure 2 35 may be opened, as shown in Fig. 4., thus giving access to the detail printing device for various obvious purposes, for example, changing the rec- 0rd material or inking ribbon and resetting the consecutive number type wheels, etc. Locking the closure 246i is but a reversal of the procedure outlined above.

The closure 2% (Figs. 1 and 4) is provided with an opening 255, covered with a transparent substance through which a liberal portion of the detail strip and the latest entries thereon are visible. An aperture 269 in the closure provides a means to permit autographing desired data on the detail strip. A finger lever 26% pro-
